This film tells the story of the technical background in the longest railway tunnel of the world: the Gotthard Basetunnel. Without the Alcatel-Lucent Enterprise network technology nothing would work in this giant building, the 57km tunnel under the Swiss Alps. Over 450 units of Alcatel-Lucent OmniSwitchâ„¢ 6855 switches connect tunnel lights, racks, power systems, doors, drainage and ventilation systems. The testimonials of the project\'s leader and area manager deliver the whole story in a content marketing approach.
